For a short time, we’re offering free worldwide shipping on the DX Commander Expedition. The kit price remains the same – the saving comes from us covering the shipping cost.
If you’re in the USA, that saving typically offsets import tariffs.
If you’re in the EU, it takes much of the sting out of the 20% VAT.
Please note: any local tariffs, duty, or VAT are collected by your courier at the point of delivery, in line with your country’s import rules. This is normal and something customers do every day – it’s straightforward and handled directly by UPS.
Once the first 100 Expedition Kits are gone, the free-shipping promotion will automatically end. The Expedition will still be available to purchase at the normal shipping rate.

https://youtu.be/xJnN5nAIFG8 – TOM’S PORTABLE EFFORT
Using a simple Coffee and Ham Radios End Fed Half Wave (EFHW) antenna and a 100-watt portable radio proves you don’t need a massive station to work serious DX. The EFHW is lightweight, easy to deploy, and efficient on its resonant band, making it perfect for portable or home setups. With 100 watts and good band conditions, that simple wire can launch a strong signal across oceans, especially when paired with smart operating—watching propagation, calling at the right time, and working the pileups strategically. It’s a great reminder that antenna placement and operating skill often matter more than raw power.
